|| Data Protection Manager Server Requirements1: Processor: 550 MHz (1 GHz or faster recommended) Operating Systems: Windows Server 2003 (Standard or Enterprise Edition) with Service Pack 1 or later installed Hard Disk2: Disk space for DPM installation: System drive: 100 MB Program files drive: 160 MB Database files drive: 900 MB Disk space for storage pool: 1.5 times the size of the protected data 2 to 3 times the size of the protected data (recommended) Memory: 512 MB RAM (1 GB RAM recommended) File Server Requirements3: Operating Systems4: Windows Server 2003 with Service Pack 1 or later Windows Storage Server 2003 with Service Pack 1 or later Windows 2000 with Service Pack 4 and Update Rollup 15 for Windows 2000 Service Pack 4 installed (This includes the configuration of Windows 2000 Server on Windows Powered Network Attached Storage (NAS) devices) Hard Disk: DPM requires enough free space on each protected volume on the file server to store the DPM synchronization log. By default, the synchronization log is 10 percent of the total capacity of the protected volume, or at least 500 MB. The file server must also have free space for installation of the DPM file agent, approximately 1 MB. Network Requirements: The DPM server and the file servers it protects must be members of the same Active Directory domain Operating Systems: The domain controllers must be running either Windows Server 2003 or Windows 2000 Server6 1. Data Protection Manager (DPM) is designed to run on a dedicated, single-purpose server. The server must not be a domain controller or application server, and must not double as the host for the DPM Management Pack. 2. The DPM server must have at least two disks installed: one that is dedicated to the system and DPM installation files, and one that is dedicated to the storage pool. 3. DPM can protect stand-alone file servers only; clustered file servers cannot be protected. 4. DPM can protect file servers running Services for UNIX or Services for Network File System, providing that case insensitivity for file names has not been disabled on the server. For information about case insensitivity, see Windows Help and Support on Microsoft web site. 5. For information about Windows 2000 Update Rollup Pack 1, see Frequently Asked Questions About the Windows 2000 Update Rollup Announcement on Microsoft web site. 6. If you plan to enable end-user recovery in a Windows 2000 domain, the domain controller must be running Service Pack 3 or later with schema modifications enabled.
